Claims.

This invention relates to record books and is concerned primarily with the casing structure of a book which is designed to proof and waterproof.

At the present time books that are employed for the purpose of keeping records in business organizations, and similar places, are subject to being destroyed in a fire, either by actual inflammation, heat of the fire, or from the effects of water 10 employed for purposes of putting out the fire, and

in view of this likelihood it has been the -prac tice to store the more important record books in fireproof places such as safes:

However, such practice is not entirely satisfactory in view of the large amount of work involved i in placing and removing the books in the safe every evening and morning, and also in view of space limitations.

With the foregoing conditions in mind this invention has in view, as its foremost objective, the

provision of a record book including a casing which in itself is substantially fully fireproof and waterproof. In attaining this objective the invention contemplates the use of a casing structure for a book which is made from sheet metal,

and hence not inflammable. In order to render the contents of the casingresistant to' effects of heat, this metallic casing is preferably lined with a heat insulating material. A particular object of the invention is the provision of a record book of the character above noted including a top part and a bottom part, and a back which is hinged to each of the top and bottom parts, respectively. The top and bottom parts carry side and front walls which interlock while the back part carries structure interlocking with the ends of the side walls.

A particular feature of the invention is the par-. ticular type of structure providing the abovenoted interlock, as the interlock is included for the purpose of excluding water from the interior I of the casing.

Various other more detailed objects and advantages of the invention will in part become apparent, and in part be hereinafter stated, as the description of the invention proceeds.

The invention, therefore, comprises a. fire and waterproof record book consisting of an outer casing'made from sheet metal and lined with asbestos. The casing includes a bottom part, a top part, and a back part, which are hinged together in the usual manner. The top part carries side and front walls whichinterlock with corresponding side and front walls on the botrender the same fire- 1939, Serial No. 262,082

tom part. The back carries partsthat interlock with the ends of the said side walls.

For a full and more complete understanding of the invention reference may be had to the following description and accompanying drawing, wherein Figure 1 Ba perspective view of a record book casing made in accordance with the precepts of this invention,

Figure 2 is a side view showing the casing in closed position, I

Figure 3 is an enlarged detailed section bringing out the interlock between the top and bottom parts,

Figure 4 is an enlarged detailed view of a portion of the hinge structure, and

I Figure 5 is an enlarged detailed sectional view of one end of the back part.

Referring. now to the drawing, wherein like reference characters denote corresponding parts, the record book of this invention is shown as comprising a bottom part referred to in its entirety by the reference character B, a top part referred to in its entirety by the reference character T, and a backing designated X.

In the illustrated embodiment, the book is shown as being one of the loose-leaf type, although it is to be clearly understood that this is to 'be no limitation on the invention.

book is of the loose-leaf type, the backing carries the leaf retaining rings In that are mounted as a unit on the spring element ll. These rings In may be opened or closed as a unit to facilitate the assembly or removal of loose leaves. If the record book is of a permanent type the same may he merely housed by the casing structure of this invention, or the back binding of the book may be permanently secured to the backing X.

The backing X at the top and bottom is formed of the side walls of the top T and bottom B, as

will be later described.

The backing X may be made from any approwith curled-over tongues l2, which define a pas-- When the priate sheet metal, such as sheet steel, and may be formed into the required shape by metal stamping operations. Inasmuchas the backing X is not of great area, it is hardly necessary to line the same with asbestos, although this may be done if the book is of large size. 5

The top T includes a fiat top wall I8, one edge of which is formed with tumed-over tongues I! which define openings aligning with the openings i3 and through which passes the hinge pintle ll. The top T has downwardly extending side walls I8, and a, front wall I9. The lower edges of each of the walls 88 and I9 may be turned back on themselves to provide a double wall of metal, as shown at 20 in Figure 3. The inner side of the top wall i6 and each of the side walls I8 and I8 carries a lining of a heat insulated material, preferably asbestos. This lining is designated 2i and on the side walls I8 and I9 is interposed between the wall proper and the turned back portion 20.

It is important to note that the lining 2| of the side wall I8 and front wall I9-extends substantially to the bottom thereof, leaving a turned over edge structurewhich may interlock with the bottom, as will be later pointed out.

It will be noted that when the book is in a closed position the rear or free edges of the side walls I8 are received in the grooves I5 of the backing X.

The bottom B comprises a fiat bottom wall 22, the inner edge of whichis of a curled-over tongue formation providing the passage for receiving a hinge pintle which connects the same to the backing X. The bottom B carries side walls 23 and a front wall 24. The metal of the side walls 23: and 24 is folded back on itself, as shown at 25, and then upwardly, as shown at 26, defining U- shaped grooves or recesses 21 which receive the lower edges of the walls I8 and I9 of the top T.

The upper edge of the wall 26 may be turned back on itself, as shown at 28, to aid in guiding the lower edges of the walls I8 and IS into the groove 21.

The bottom wall 21 of the bottom B is preferably lined with asbestos, as are the side walls 23 and front wall 25 up to theflange structure providing the groove 21. It will be noted that the flange structure 25.and,26 on the side walls does not extend completely back to the free edge of the wall (see Figure 1), this to permit of the reception, of the free edge of the wall in the grooves I5 when the book is closed. I I

As clearly brought out in Figure 2, a hasp 29 is 'pivotally carried by the front wall I9 of the top T, while a staple 30 the hasp ,29 is carried by which cooperates with the front wall 24 of the bottom B. A padlock shown-at 3| may be inserted in this staple to lock the box in a closed position in a well-known manner.

While a preferred specific embodiment of the invention is hereinbefore set forth it is to be clearly understood that,the invention is not to be limited to the exact construction illustrated and described, because various modifications of "these details may be provided in putting themvention into practice within the purview of the appended claims.
